Problem waking up from sleep

[bigseb]

Not sure if this is the right forum...

Sometimes my PC has trouble waking up from sleep. This morning, for example, the mouse and the keyboard wouldn't work. I had to press the 'on' button to wake it up. The log in screen appears but no mouse or keyboard to use to type in password or to restart. Other times its just the mouse. Unplugging the mouse and plugging it back in doesn't help either. Same goes for keyboard.

There have also been times when the PC takes up to ten minutes to wake up. That's happened 3 times.

Other times, maybe half, it works perfectly.

Really have no idea what's causing this. All help welcome!

Do you have a PS/2 keyboard and mouse or USB?

For USB problems...

• Start with http://www.sevenforums.com/tutorials/165554-usb-driver-general-fix-problems.html to resolve the USB issues. Also, USB ports can sometimes enter a safe power state to protect the system from power surges due to USB devices. To reset the USB ports to a nominal power state:
  
  1. Shut down and turn off the computer.
  2. Unplug the computer from the wall or surge protector (then remove the battery if it is a laptop).
  3. "Remove the computer from any port replicator or docking station, disconnect
     cables to printers or devices such as external monitors, USB memory sticks or SD cards, headset or external speakers, mouse or auxiliary keyboard, turn off WIFI and Bluetooth wireless devices." (Use Hard Reset to Resolve Hardware and Software Issues HP Pavilion dv5000 Notebook PC series - HP Customer Care (United States - English))
  4. Hold down the power button for 30 seconds. This closes the circuit and ensures all
     power from components is drained to clear the software connections between the BIOS
     and hardware and clear any corruption in the temporary memory.
  5. (If it is a laptop, plug the battery back into the laptop and then) Plug the computer back into the wall. Do not reconnect any unnecessary peripherals; monitor, keyboard,
     and mouse should suffice and be the only peripherals reconnected.
  6. Turn it on to reinitialize the software connections between the BIOS and hardware

Those steps require that you remove the devices causing problems. You obviously cannot do so with the keyboard and mouse, but please remove any other USB devices you have connected. It is possible other devices might causing conflicts with the mouse/keyboard USB devices.
